Definitions

  • the invention relates to a stiffening profile for a vehicle support frame which connects two pillars of the vehicle support frame, in particular the C-pillars or D-pillars, as a vehicle transverse wall on the floor side and merges into rounded pillars at its ends formed as pillar connection zones via rounded corner reinforcements.
  • a suitable measure to achieve increased stiffness is to additionally stiffen the vehicle support frame by installing stiffening profiles oriented transversely to the direction of travel as transverse walls of the vehicle.
  • Such stiffening profiles are known from practice.
  • Such a known stiffening profile consists of a shell component designed as a hat profile, which in the installed state connects the columns to be supported on the floor side and is thereby welded to the floor panel.
  • the stiffening profile is supplemented by additional rounded corner reinforcements, which encompass the profile as well as the respective column at the corners formed by a column and a profile end connected to them by welding. Due to the rounded shape of the corner reinforcements, the horizontal outer surface of the hat profile is even into the side surface of the column facing the stiffening profile, which results in the desired uniform force profile.
  • the corner reinforcements are also formed by shell components, whereby each corner reinforcement is usually composed of two parts for reasons of forming technology. Consequently, in addition to the actual hat-shaped shell component connecting the columns, four further parts to be connected in pairs with one another and with a column or the profile are required in order to realize a stiffening profile for connecting two columns with sufficient support function. With the large number of different parts, there are high costs both for their individual production and for the assembly of the parts. In addition, a variation of the dimensions of the stiffening profile is only possible with considerable effort, since newly designed tools for the individual parts have to be provided for this purpose.
  • the design-related high number of welded connections has a negative effect, since these have a significantly lower strength compared to the base material and therefore represent a factor which reduces the fatigue strength of the construction.
  • stiffening profile of the type mentioned by which the rigidity of the vehicle support frame is effectively increased, which is characterized by low manufacturing costs and, moreover, its dimensions can be varied without great effort.
  • This object is achieved with a stiffening profile according to the preamble in that the stiffening profile and the corner reinforcements are designed as a one-piece double shell made of an internal high-pressure formed double plate welded on its peripheral edge.
  • the stiffening profile according to the invention even in the case of complex spatial shaping, consists of a simple base body, namely the one-piece double shell produced with the help of hydroforming technology (IHU). Due to the high variability in terms of the shape to be produced, it is possible to form the rounded corner reinforcements necessary for improved support and a uniform force distribution between the two pillars of the vehicle structure in one piece with the stiffening profile, thereby creating large, usable pillar connection zones. In contrast to the state of the art, in addition to the actual profile, no further individual components have to be manufactured and assembled, which means that production costs can be significantly reduced. Another consequence of the variability mentioned is that the dimensions of the stiffening profile can be comparatively easily adapted to the requirements of the user.
  • the number of joints can be reduced to a minimum, so that the strength of the base material can be optimally used, especially when using high-strength steel materials, and thus excellent support properties can be achieved.
  • the circumferential edge of the double plate remains in the stiffening profile for manufacturing reasons as an edge protruding from the top of the profile and extending over the entire length of the profile. This top edge can be used as a flange for receiving seals or for mounting cladding parts.
  • the stiffening profile also has edge regions bent at right angles on the bottom side for connection to the floor panel of a vehicle body. These form easily usable connection zones, for example for a welded or soldered, but also adhesive connection.
  • the object of the invention is further achieved with a method for producing the stiffening profile according to the invention, which comprises the following method steps:
  • the IHU technology uses a process that allows the user a high degree of design freedom with regard to the shape to be produced.
  • the particular advantage of the IHU technology with regard to the material properties of the formed component, for example, compared to deep drawing, is that in the case of the IHU, the material to be formed is stretched much more intensely and homogeneously. This material stretching can intensify the “bake hardening” effect, in particular in the case of high-strength steels, ie the additional strength increase in heat treatment at relatively low temperatures, for example by means of a varnish bake.
  • the strength values that can be achieved thereby enable a further reduction in the necessary material thicknesses and thus contribute a reduction in the total vehicle weight.
  • the peripheral edge of the double plate is welded on the end face by laser beam welding. It is a reliable and easy to automate joining process.
  • the double plate is shaped symmetrically with respect to its longitudinal axis and is divided along this longitudinal axis, so that two identical stiffening profiles are produced.
  • the identically shaped profiles can then be installed in the same place in two vehicles, for example.
  • FIG. 2 shows the stiffening profile of FIG. 1 in section along the line II-II of Fig.l
  • FIG. 3 shows the stiffening profile of FIG. 1 in the installed state in a perspective sectional view
  • Fig. 5 two stiffening profiles made of an asymmetrical double plate in the installed state in a schematic view.
  • the stiffening profile comprises a straight central region 5 with a substantially U-shaped cross section, which at its two ends merges into rounded corner reinforcements 6, 7. As a result, large open column connection zones 6a, 7a are formed, which have a uniform force curve between two on the Enabling stiffening profile supported columns of a vehicle support frame.
  • the front welded edges 2a, 3a of the individual boards 2, 3 together form a top edge 4 in the stiffening profile, which can be used as a flange for receiving seals or for mounting cladding parts.
  • the stiffening profile comprises edge regions 2b, 3b which are bent at right angles at the bottom and which form well usable flanges for connecting the stiffening profile to a floor panel.
  • the stiffening profile is shown in the installed state.
  • the open pillar connection zone 7a encompasses a pillar 8 of a vehicle support frame, preferably a C or D pillar, and is connected to it, for example, via welding points (not shown).
  • the stiffening profile is supported on a base plate 9 and connected to it at the bent edge regions 2b, 3b by weld seams 9a.
  • FIG. 4a-c show the individual process steps for producing the stiffening profile.
  • FIG. 4a shows a double blank 10 consisting of two single sheets lying flat on top of one another, which is preferably joined at its peripheral edge by laser beam welding.
  • the board is slightly asymmetrical with respect to its longitudinal axis.
  • a peripheral edge region 10a of the plate 10 is clamped between the forming tool halves and thus in the reshaped component as a flat, outwardly facing edge is retained (Fig. 4b).
  • the formed double blank 10 is cut laterally along the lines 11 and then divided longitudinally along the line 12, whereby two differently shaped stiffening profiles 13, 14 with corner reinforcements are formed.
  • the lower edges 13a, 14a, the stiffening profiles 13, 14 are preferably produced at the bottom at right angles, which facilitate the connection of the stiffening profiles to a floor panel.
  • stiffening profiles 13, 14 produced in the above manner are shown schematically in the installed state.
  • the stiffening profiles 13, 14 are each arranged between a pair of columns 16, 17 of a vehicle support frame and connected to it by welding. Furthermore, each of the profiles 13, 14 is supported on a body floor panel 15 and is also connected to this by welding.
